Apply aircraft electrical system design techniques

Assessment tool

Version 1.0
Issue Date: May 2024


This unit of competency applies to design of aircraft electrical systems and components for aircraft, design of modifications and development, and update of test procedures and of repair requirements. It includes electrical design techniques and performance of the design process within the requirements of airworthiness regulators and documentation of the design process within management systems, such as configuration management (CM) and integrated logistic support (ILS).

It is suitable for people working as members of design teams and for those employed within maintenance engineering support departments or pursuing careers and qualifications as paraprofessionals in avionic engineering.

This unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
